Answer:
(y+5)²
Step-by-step explanation:
Every perfect square trinomial, completes the rule:
(a+b)²=(a²+2ab+b²)
Let's complete the PST:
(a) would be the square root of y², which is y.
(b) would be a number that multiplied by 2y gives us 10y, which is 5.
Our perfect square trinomial is y²+10y+25
Finally, using the mentioned rule, the binomial square for that equation is (y+5)²
The absolute value for that is 21-63
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
5x + (-2) = 6x + 4
Step 2: Simplify
5x - 2 = 6x + 4
Step 3: Subtract 5x on both sides
-2 = x + 4
Step 4: Subtract 4 on both sides
-6 = x
Step 5: Rewrite
x = -6
1 because 11 can only go into 16 once
